Finally able to cross this line off my list - I ordered the Obi-Wan, Rey, Kylo Ren, Grievous and Darth Maul from WalMart and then I grabbed the Boba Fett off eBay, so while I didn't really need the packaging variants, the entire run of 3.75" GoA figures are in my collection now.
I will not be collecting the 5" scale ones - I have zero interest in starting another scale.
